Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам чугуна, который может быть использован для изготовления изделий, работающих в условиях термоциклирования.The invention relates to the field of ferrous metallurgy, in particular to compositions of cast iron, which can be used for the manufacture of products operating in thermal cycling.
Известен чугун, содержащий, мас.%: углерод 1,0-4,0; кремний 0,1-2,5, марганец 0,1-15,0; магний 0-1,0; вольфрам 0-5,0; молибден 0-2,0; ниобий 0-2,0; железо остальное [1].Known cast iron, containing, wt.%: Carbon 1.0-4.0; silicon 0.1-2.5, manganese 0.1-15.0; magnesium 0-1.0; tungsten 0-5.0; molybdenum 0-2.0; niobium 0-2.0; iron the rest [1].
Задача изобретения состоит в повышении термостойкости чугуна.The objective of the invention is to increase the heat resistance of cast iron.
Технический результат достигается тем, что чугун, содержащий углерод, кремний, марганец, магний, вольфрам, молибден, ниобий, железо, дополнительно содержит алюминий при следующем соотношении компонентов, мас.%: углерод 3,0-3,5; кремний 0,5-1,0; марганец 0,4-0,8; магний 0,05-0,1; вольфрам 2,0-3,0; молибден 2,0 - 3,0; ниобий 2,0-3.0; алюминий 0,05-0,1; железо остальное.The technical result is achieved in that the cast iron containing carbon, silicon, manganese, magnesium, tungsten, molybdenum, niobium, iron, additionally contains aluminum in the following ratio of components, wt.%: Carbon 3.0-3.5; silicon 0.5-1.0; manganese 0.4-0.8; magnesium 0.05-0.1; tungsten 2.0-3.0; molybdenum 2.0-3.0; niobium 2.0-3.0; aluminum 0.05-0.1; iron the rest.
В таблице приведены составы чугуна.The table shows the composition of cast iron.
Повышение термостойкости чугуна достигается за счет комплексного влияния компонентов, присутствующих в его составе. Ниобий и молибден упрочняют твердый раствор. Вольфрам обеспечивает чугуну твердость при повышенных температурах, улучшает его металлическую основу. Алюминий и магний выполняют функцию раскислителей, способствуют измельчению зернаThe increase in heat resistance of cast iron is achieved due to the complex effect of the components present in its composition. Niobium and molybdenum strengthen the solid solution. Tungsten provides cast iron hardness at elevated temperatures, improves its metal base. Aluminum and magnesium act as deoxidizers, contribute to the grinding of grain
Чугун выплавляют в электропечах и отливают формы. С целью предотвращения отбеливания, вызываемого присадкой магния, чугун последовательно модифицируют магнием или его сплавами и высококремнистым ферросилицием. Отливки подвергают низкотемпературному отжигу при температуре 600°С для снятия линейных напряжений.Cast iron is smelted in electric furnaces and molds are cast. In order to prevent bleaching caused by an additive of magnesium, cast iron is subsequently modified with magnesium or its alloys and high-silicon ferrosilicon. The castings are subjected to low-temperature annealing at a temperature of 600 ° C to relieve linear stresses.
